Since we can only take the gradient of a vector in FLUENT, to calculate laplacian of a vector whose value is stored in a UDS C_UDSI(c,t,0), for example two dimensional d2f/dx2+d2f/dy2, you can use...

Dear Amir,
I tried to store the diffusion coefficients of a UDS to another UDS (in VOF method, there is UDS for the mixture), that is C_UDSI(c,t,1)=C_UDSI_DIFF(c,t,0), then take the gradient....

Dear Amir,
I tried your advice, however not very successful.
Interestingly I tried to use define_execute_at_end instead of define_adjust, there is no more such error message.
Thank you all...

Dear Amir,
Recently I modified my UDFs. They are doing their job only expect there is a Define_Adjust macro causing problem.
I have to run the scalar equation a few iterations before I hook the...

Dear Amir,
I tried to create my own C file as Define Source
Basically I want to determine first whether a cell has both liquid and air phase. If so, the source will be returned to momentum...
